Injectable use is preclinical/off-label, research-use-only, with no human clinical trials. | | Mechanism of Action | A New Class of Signaling Molecule MOTS-c belongs to the mitochondrial-derived peptides (MDPs) - a class of small peptides encoded within mitochondrial DNA open reading frames that were historically thought to encode only ribosomal RNAs. The known MDPs include:… | GHK-Cu works mostly as a copper shuttle and a signaling peptide. It binds Cu(II) with high affinity (log K around 16.4, close to albumin's 16.2) and can supply or regulate copper for copper-dependent enzymes like SOD1, lysyl oxidase, cytochrome c oxidase, and… | | Half-Life | ~4–6 hours | ~30-60 min (plasma; approximate legacy figure, no robust modern human PK study) | | Typical Dose Range | 5,000–10,000 mcg (5–10 mg) per injection | 200-500 mcg SC daily (community/RUO; no clinically established injectable dose) | | Dosing Frequency | 2-3 times per week | Once daily subcutaneous; some run 5 days on / 2 days off. Topical: 1-2x daily to cleansed skin. | | Administration | Subcutaneous, Intramuscular | Subcutaneous, Topical | | Side Effects | Reported Effects (limited human data) - Injection site reactions — Mild erythema, transient itching at SC injection site. Site rotation minimizes. Probably the single most reported issue. - Transient fatigue — Some users report mild fatigue in the first week… | Topical GHK-Cu is generally well tolerated; higher-concentration formulations (4-5%) raise the odds of irritation, redness, or stinging. Injectable use has no safety data from controlled trials; the main theoretical concern is copper accumulation with repeated… | | Molecular Weight | 2174 Da | Free peptide (GHK): 340.38 Da (C14H24N6O4).

MOTS-c is a longevity & cellular health that a new class of signaling molecule mots-c belongs to the mitochondrial-derived peptides (mdps) - a class of small peptides encoded within mitochondrial dna open reading frames that…. GHK-Cu is a skin, hair & aesthetics that ghk-cu works mostly as a copper shuttle and a signaling peptide. it binds cu(ii) with high affinity (log k around 16.4, close to albumin's 16.2) and can supply or regulate copper…. The two differ in mechanism, half-life (~4–6 hours vs ~30-60 min (plasma; approximate legacy figure, no robust modern human PK study)), and typical dose range. ### Which has the longer half-life, MOTS-c or GHK-Cu? MOTS-c has a half-life of ~4–6 hours. GHK-Cu has a half-life of ~30-60 min (plasma; approximate legacy figure, no robust modern human PK study). Longer half-lives generally mean less frequent dosing but slower on/off kinetics. ### Which is cheaper, MOTS-c or GHK-Cu? Lowest listed price on BodyHackGuide: MOTS-c from $44.99, GHK-Cu from $34.99. Prices are pulled from the vendor listings tracked on BHG and change frequently. See the compare tables on each compound page for the current set of offers. ### Can you stack MOTS-c and GHK-Cu? Stacking depends on mechanism overlap, safety profile, and goals. MOTS-c and GHK-Cu should only be stacked after reviewing each compound's individual protocol page, side effect profile, and any published interaction data. Use the BodyHackGuide stack builder for a structured review before combining research compounds. ## See current vendor prices Listings from the vendors we track.
